BALL-BEARING.

Specification of Letters Patent.

Patented Apr. ML, 1914.

Application filed November 14, 1908. Serial No. 462,699.

To all w]: am it may concern.

Be it known that I, LOUIS I. Moonns, a citizen of the United States,residing at Geneva, in the county of Ashtabula and State of Ohio, haveinvented a certain new and useful Improvement in Ball-Bearings, of whichthe following is a full, clear, and ex act description, reference beingbad to 'the accompanying drawings.

My invcnthm relates to ball bearings and more particularly appertains toa means for fastening the ball retaining means in proper position, andfurthermore, to so form the raceway for the balls that each ball willcontact with the sahlraceway at four points only. V

Generally speaking, the invention comprises the elements andcon'ibinations thereof set forth in the accompanying claim.

Ieference should be had to the accompanying drawings forming a part ofthis specification in which Figure- 1 is a side elevation of the ballbearing; Fig. 2 is a central transverse cross section of Fig. 1; Figs. 3and 4 are the cooperating sections of the inner ring member of thebearing; Fig. 5 is a diagrammatic illustration showing the contactingpoints of the balls with the raceway, as well as showing the retainingmember.

The ball bearing herein shown and described comprises an outer ringmember or ball cup 1 and an inner ring member, the said inner ringmember comprising the two cooperating sections or cones 2 and 3. Thepart 2 of the inner ring is formed with a projecting flange 4 which isof less external diameter than the outer part; of the ring therebyforming a shoulder The part 3 is formed of an internal diameter toclosely fit the walls of the flange 4 and both of these members whenassembled are formed with a continuous groove 6. The inner side of thering 1 is likewise formed with a groove 7, and the grooves 6 and 7 inthe inner and outer ring members, form the raceway in which the ballsare adapted to travel. The formation of the walls of the grooves 6 and 7is of a shape such that the balls will contact with the 'walls thereofonly at four points, as will be clearly seen in Fig. 5. In

'this way the friction between the balls and the moving part will bematerially reduced as against a construction where the ball is insubstantial contact with the points of its raceway. 'Again, by providingfour points of contact between the balls and the walls of the raceway,the outer and inner rings are always correctly alined with respect toeach other, and whatever side thrustthere may be between the outerandinner ring members relative to each other, the thrust will be borneat only two points upon each ball and thereby the friction will bereduced.-

As before stated, the part 3 is adapted to engage the outer portion ofthe flange 4 and to seat itself upon the shoulder 5 in which position,the grooves in the parts 2 and 3 will cooperate to form thecompletedinner raceway for the balls.

As a means for securing 'the retaining member 3 in place, I haveprovided the following construction: The flange 4 is provided with agroove 8 extending entirely around it, near the outer end thereof, andthe inner portion of the member 3 flares outwardly toward the top and atthe bottom of t-lhe flaring portion is formed with a. shoul- L er 9.

The parts just described are so' proportioned that when in assembledposition, the shoulder 9 is at the inner edge of the groove 8. hen inassembled position, a wire ring 10 is crowded into the semi-circulargroove 8, which ring at the same time will bear upon the shoulder 9. Thering when in the position shown in Fig. 2 will hold the ball retainingring 3 against outward movement by virtue of its cooperation with theflange 9. The ring 10 is made of such diameter as to closely fit withinthe groove 8. Preferably this ring is made of soft metal which possessessuflieient strength to hold the ring 3, but may be readily cut out byusing a suitable sharp tool.

In assembling the bearing. the member 9. is laid upon a flat surface andthe member 1 is slightly raised so as to allow suflicient openingbetween the curved raceway portions in the members 1 and 2 to slip theballs in place. hen all the balls are in place, the member 1 is loweredso as to be in the same plane as the part 2 and the retaining ring 3 isplaced in position. Next the wire ring 10 is forced into the positionshown in Fig. 2, in which position the bearing is comlete. p If it bedesired to dis-assemble the members of the bearing for any-purpose, theentire bearing is placed in a suitable chuck and inasmuch as the wire.10is formed of soft material, the same may be removed by any sharinstrument. If it is convenient, the bearing may be placed in the chuckof a lathe, and the member 2 held against rotation, whereupon a toolwith a long sharp point may be inserted into the space between themember 2 and the retaining ring 3, which upon the operation of thelathe, will cut the ring so that the ring 3 may be readily removed.

The construction I have described is very convenient, when it is desiredtoadjust the members 2 and 3 for wear. The soft metal ring beingremoved, the members 2 and 3 removable ring constituting another por-.tion of the same raceway and having a carrying the shoulder beingflared away from the groove to afford a space for the insertion of thewire or for the. insertion of a wire removing tool, the throat of theopen ing thus provided to the groove being narrower than the wire whenin place, a grooved annular membercompleting the raceway of the bearing,and a pluralityofballs in said raceway.

In testimony whereof, I hereunto aflix my signature in the presenceoftwo-witnesses. LOUIS .P, MOOERS.
